This wall mount, switching power supply has selectable regulated output voltage of 3.0, 4.5, 6.0, 7.5, 9.0, and 12.0 V DC. Six common connectors are provided, each of which can be inserted two ways to determine the output polarity. This power supply features a U.S. style mains plug only, as shown, but supports AC input voltage of 100-240V at 50 or 60 Hz.

To use with systems that require regulated 3.3V or 5V

This supply doesn't have a 3.3V or a 5V setting, and some microcontroller systems don't have a voltage regulator on them, in which case you wouldn't be able to connect this supply directly. When this is the case, you can connect this supply to the MIKROE-192 Dual 5V/3.3V DC Regulator Board then source the power from the MIKROE-192's screw terminals. If your system has a 2.5mm barrel power jack, connect the PWR-CABLE barrel jack adapter. If it has a 2.1mm barrel power jack, one solution is to run a couple wires between the MIKROE-192 and the PRT-10287 adapter.

A simpler solution for a 5V system with a 2.1mm barrel jack is to connect this supply to the DCDC6-16-TO5 regulator board which has a USB output, then connect the TOL-08639 USB-to-Barrel adapter into that.

If your 5V system needs to source more current than this supply can provide, consider the TOL-11456 (1A) or WA-USB-2A power supply, each of which uses a USB cable delivery, so the TOL-08639 USB-to-Barrel adapter is handy if your system has a 2.1mm barrel jack.
